Table 1. First-Order Raman Bands and Vibrational Modes of Soot and Graphite According to Sadezky et al.⁴² for Interpretation of the Obtained Raman Spectra (vs = Very Strong, s = Strong, m = Medium, and w = Weak)^a.

	Raman shift [cm^–1]
band	soot	disordered graphite^c	vibrational mode^b
G	∼1580, s	∼1580, s	ideal graphitic lattice (E_2g symmetry)
D1	∼1350, vs	∼1350, m	disordered graphitic lattice (graphene layer edges, A_1g symmetry)
D2	∼1620, s	∼1620, w	disordered graphitic lattice (surface graphene layers, E_2g symmetry)
D3	∼1500, m		amorphous carbon (Gaussian line shaped)
D4	∼1200, w		disordered graphitic lattice (A_1g symmetry), polyenes, and ionic impurities

Minor changes in the Raman shifts may occur because of the different measurement parameters.

Lorentzian line shaped unless otherwise mentioned.

Polycrystalline graphite (<100 nm) and boron-doped highly oriented polycrystalline graphite (HOPG).
